Abstract

In a circular cold saw (1) with a saw blade (6) entering during sawing into the material (5) to be worked from below through a slot (4) in a support plate (3) of a support table (2), the direction of rotation of the saw blade (6) during sawing is selected in such a way that the saw teeth (11) cutting in each case move away from the pivot bearing (7) of the saw-blade arm (8). This results in a position of the resultant of the cutting force at a slight distance, if any, from the pivot bearing (7) so that the feed is considerably relieved of load relative to a reversed direction of rotation of the saw blade (6). <IMAGE>
